Answer:

y = -1/5x -4

Step-by-step explanation:

We know the y intercept is -4 since it crosses the y axis at -4

The slope is negative since it goes down from left to right

Take two points on the line

(0,-4) and (5,-5)

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

= ( -5- -4)/( 5 -0)

= (-5+4)/ ( 5-0)

= -1/5

The equation for the line in slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = -1/5x -4

Answer:

B and D

Step-by-step explanation:

Take a look at all the options x=4, 3, 1, 2 > 0

So, we just care about the domain where x>0, which is $f(x)=x^{2}$ .

Then plug in x we will have the right answer.
